Cantilever Beam with Distributed Load Calculator
This calculator is used to analyze the behavior of a distributed loaded beam. Distributed loads can be applied at different intensities and distributions along the beam.
The Cantilever Beam with Distributed Load Calculator is a tool used to analyze the structural behavior of cantilever beams subjected to distributed loads. Unlike concentrated loads applied at a single point, distributed loads act over a length of the beam, more accurately representing many real-world loading scenarios. This calculator determines key parameters such as reaction forces and moments, bending moment and shear force distributions, and beam deflection. This analysis is crucial for ensuring the structural integrity and safety of cantilever beams in various engineering applications.
When using the online Cantilever Beam with Distributed Load Calculator, you can calculate these parameters by entering: Externally applied load, Elastic modulus, Area moment of inertia, Length of the beam, and Load position.
- Slope at free end = PL3 / 6EI
- Deflection at any section = Px2( x3 + 6L2 – 4Lx ) / 24EI
The variables used in the formula are:
- P: is the externally applied load,
- E: is the Elastic Modulus,
- I: is the Area moment of Inertia,
- L: is the Length of the beam and
- x: is the position of the load

Understanding How to Calculate a Distributed Loaded Cantilever Beam
The Cantilever Beam with Distributed Load Calculator simplifies the analysis of beams under distributed loads. Here’s a breakdown of the calculation process:
- Determination of Load Distribution: The calculator accounts for the load distribution applied along the cantilever beam. This distribution, which can be uniform or non-uniform, is a crucial input.
- Calculation of Reaction Forces and Moments: The calculator determines the reaction forces and moments at the fixed support of the cantilever beam. These reactions are essential for maintaining static equilibrium.
- Calculation of Shear Force and Bending Moment Diagrams: The calculator generates shear force and bending moment diagrams, which illustrate the internal forces within the beam. These diagrams are essential for determining the beam’s strength and deflection characteristics.
- Evaluation of Beam Strength and Deflection: The calculator uses the calculated shear forces and bending moments, along with the beam’s material properties and dimensions, to evaluate its strength and deflection. This ensures that the beam can safely withstand the applied load.

What is a Distributed Loaded Cantilever Beam?
A distributed loaded cantilever beam is a structural element characterized by its support condition and the nature of the applied load. As with all cantilever beams, one end is fixed or rigidly supported, while the other end is free and unsupported. However, unlike beams subjected to concentrated loads at a single point, a distributed load acts over a length of the beam. This distributed load can be uniform, meaning it has a constant intensity along the beam, or non-uniform, with varying intensity. This type of loading is common in many engineering applications, such as a floor slab extending over a support or wind pressure acting on a structure.
Detailed Explanation of the Basic Properties of a Distributed Loaded Cantilever Beam
A distributed loaded cantilever beam exhibits specific structural properties that influence its behavior under load:
- Fixed and Free Ends: The beam has one end rigidly fixed, preventing both translation and rotation, and one end that is free to deflect and rotate.
- Distributed Load: The load is spread over a length of the beam, which can be uniform or non-uniform.
- Reaction Forces and Moments: At the fixed support, there is a reaction force and a reaction moment that resist the applied load and maintain equilibrium.
- Shear Force: The shear force within the beam varies along its length, depending on the distribution of the applied load.
- Bending Moment: The bending moment also varies along the beam, with the maximum moment typically occurring at the fixed support.
- Deflection: The beam deflects under the distributed load, with the maximum deflection occurring at the free end. The Cantilever Beam with Distributed Load Calculator calculates this.
- Slope: The slope of the deflected shape varies along the beam, with zero slope at the fixed end and maximum slope at the free end.
Detailed Explanation of How to Calculate a Distributed Loaded Cantilever Beam
Calculating the behavior of a distributed loaded cantilever beam involves applying principles of structural mechanics. The Cantilever Beam with Distributed Load Calculator performs these calculations, but a deeper understanding is valuable:
- Determination of Load Distribution: The first step is to define the load distribution, which can be expressed as a function of position along the beam.
- Calculation of Equivalent Point Load and Location: For complex distributed loads, it’s often useful to determine an equivalent point load and its location for simplified calculations.
- Calculation of Reaction Forces and Moments: Equilibrium equations are used to determine the reaction force and moment at the fixed support.
- Formation of Shear Force and Bending Moment Equations: Equations for shear force and bending moment as functions of position along the beam are derived.
- Integration to Find Slope and Deflection: The bending moment equation is integrated to find the slope, and the slope equation is integrated to find the deflection. Boundary conditions (zero slope and deflection at the fixed end) are applied to solve for constants of integration.
The Cantilever Beam with Distributed Load Calculator automates these steps.
Detailed Explanation of the Diverse Applications of Distributed Load Cantilever Beam Calculation
Distributed load cantilever beam calculations are essential in many engineering and structural design applications:
- Structural Engineering: These calculations are used in the design of building structures, bridges, and other civil engineering projects where cantilever beams are subjected to distributed loads, such as floor loads, wind pressure, or snow loads. The Cantilever Beam with Distributed Load Calculator is crucial here.
- Aerospace Engineering: Aircraft wings experience distributed aerodynamic loads, and accurate calculations are essential for ensuring structural integrity.
- Mechanical Engineering: Machine components, such as robotic arms and machine tool supports, often function as cantilever beams with distributed loads.
- Civil Engineering: Retaining walls, which resist the distributed pressure of soil, are analyzed using these calculations.
- Construction: Temporary structures, such as formwork for concrete, are designed using distributed load cantilever beam calculations.
